Blox Composite Nylon Velocity Stack, 4" Inlet, 6" Diameter

The BLOX Racing Intake Velocity Stacks are designed to optimize and maximize the entry of air flow entering the vehicle's induction system. In short, the low velocity air flow taken through the air filter is turned into a smooth, high velocity intake charge.

The BLOX Racing Intake Velocity Stacks feature 3” OD outlets and are available in composite nylon and high quality billet aluminum. Both types are designed to work in conjunction with BLOX Racing air filters or ther filters with 6” OD flanges.
